Well along with presentations, I want to show this model that I built myself, it took 8 months to make 3D models, learning only with tutorials on "youtube", mastered this art.
This model is the General grievous clone wars version, which will be constructed in real-sized paper, here I want to make an advance on my model, you can have some corrections in the process, also will have textures, I hope I hope you enjoy your opinions.

If you are planning on making it life-sized, you might want to put more details in the curved parts of the mesh. Mostly the head and the round parts of the joints.
Great work! I'm still learning to model in 3d as well. I wish all the best of luck to you! Keep up the good work!
